Katy Perry in Lip Synch Snafu at French Awards Show

Singer Katy Perry can dance, but she lost a shuffle with a backing vocal track over the weekend.

Perry, a vocal proponent of President Barack Obama, was performing at the NRJ awards show in France when a technical glitch interrupted her song Roar. Her backing vocal track went awry, and a member of the event’s team approached the singer to kindly ask her to start the song anew.

It seems like that “little problem” refers to the fact that the entirely wrong back track was playing. Although, the error contributes to the impression that Perry is not performing her vocals live. When the song restarts (at about 1:37), she at least appears to be singing for real.
